GC126N Gas chromatograph

GC126N  Gas chromatograph 

Technical Features:

● The host machine adopts a 7-inch color touch screen with friendly man-machine interface.

● Computer backcontrol and host touch screen to achieve synchronous bidirectional control.

● The multi-core, 32-bit embedded hardware system ensures the reliable operation of the instrument.

● Carrier/hydrogen/air flow (pressure) digital display.

● Gas shortage alarm protection function; Heating control protection function (when opening the door of the column box, the motor of the column box fan and the heating system will shut down automatically).

● Split flow/split ratio can be automatically controlled to save carrier gas.

● Configure automatic sampler installation and positioning interface to match automatic sampler of various specifications.

● Data acquisition is a standard dual-channel data acquisition card with a sampling time of 50ms.

● Using logarithmic amplification plate, detection signal no cut-off value, synchronous external trigger function, can be started by external signals (automatic sampler, thermal analyzer, etc.) at the same time the host and workstation.

● It has perfect system self-check function and fault automatic identification function.

● With eight external event extension function interface, can be selected with a variety of control valves, and according to their own set time sequence work.

● The external link mode is network port connection (RJ45), which provides convenience for remote control of data.
